Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).

What factor is the difference between speed and velocity?

Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE


How would you differentiate speed time distance and velocity?

Velocity is a vector: it has a direction. The others are all scalars. The dimensions of the scalars are Speed : [LT-1] Time: [T] Distance: [L]


How velocity is different from speed?

velocity is speed with a direction. speed would be like 35mph. velocity would be like 35 mph south


What is the speed and velocity triangle formula?

Velocity = Speed / Time So, in the context of a triangle, speed would be at the top.


Does a cars speedometer measure speed or velocity or both?

A speedometer measures speed only and not velocity. Velocity is a measure speed of travel and the direction of travel. A GPS unit would measure velocity as it would measure both speed and direction of travel.


Can an object have a varying speed if its velocity is constant?

No, velocity is a vector quantity and measures both speed and direction. If the velocity of an object is constant then that would also mean the speed would stay constant.


Is speed a component of scalar?

Yes, velocity would be the vector companion of speed, as velocity must have a direction.


How would you differentiate speed of reaction and timing?

What is the metric unit that a wave's velocity is measued in?

The speed of anything is measured in metres per second. The difference between speed and velocity is that velocity is a vector, that is it has direction and well as magnitude. So velocity would be measured in metres per second in a certain direction.


Is 80 kilometers per hour velocity?

Yes. If you divide a distance by a time, you get a speed or a velocity. Actually, in physics this would be called a speed; a velocity would also include a direction. But in popular language, "speed" and "velocity" are used interchangeably.


Speed in a certain direction?

That would be velocity


Why we does not use speed instead of velocity?

When the direction of motion is relevant, you would use velocity rather than speed.


What would have to be true for the velocity to be constant?

the speed would have to change.


What is an objects velocity?

Velocity is speed with a direction. For Example 30 Miles/hour East would be velocity.


How fast something moves is?

That would be velocity.


How is velocity and acceleration related?

velocity is the speed at which you are traveling, acceleration is the rate you are increasing or decreasing in velocity. If you are going at constant velocity, you are not increasing or decreasing speed, therefore your acceleration would be zero.-@mikesbabygurl13@


When can an object a constant speed but not a constant velocity?

Consider an object turning in a circle at a constant speed. Because velocity is not just the value of speed, but also the direction in which the object is moving, the velocity would not be constant.


What information would be needed to determine the speed of an object?

Two position measurements and the time between the measurements will give the average velocity (i.e. speed and direction).


Which of the following would be a change in velocity but not in speed?

Velocity is a vector quantity, i.e. it consists of two measures, one is speed, the other is direction. If the speed remains constant then a change in direction would alter the velocity. (you didn't list any examples)


What is measure in meters per second?

Speed, or velocity. For velocity you would also need a direction.


What is a example of a change in velocity withouth a change in speed?

Well velocity is mass * acceleration, so if you add weight while keeping the same speed, that would be a change in velocity.


Which of these references a velocity (not speed)?

I would say vector


What is an example of the word velocity?

Velocity means speed or speediness. When you drive a car at 55 mph, that would be it's velocity. It does have an upper limit of velocity. It can also mean the rate of change in speed. You can also look at it as the speed that gets you get up to 55 mph.


How would the velocity of an object change when the speed stays the same?

Velocity includes both speed and direction, so velocity will change when an object changes direction while maintaining it's speed. An example is a car at constant speed around a curve.


Can an object have a constant speed but not a constant velocity?

Yes. Velocity is made up of speed and direction (i.e. 12mph North). So a car driving in a circle could have constant speed, but its velocity would be continually changing.
